It detects heat through a dual-sensing approach: a fixed threshold at 135 degrees Fahrenheit and a rate-of-rise trigger if temperatures climb more than 15 degrees in one minute. This combination helps you notice potential heat events early, without the nuisance alarms that can come from smoke detectors in drafty or busy spaces.\u003c\/p\u003e\n\u003cp\u003ePowered by a 120-volt AC connection with a 9-volt battery backup, the unit remains functional during power outages, helping maintain awareness even when the lights go out. A microprocessor controls the sensing logic to reduce unnecessary alerts, so you’re less likely to be disturbed by non-threatening fluctuations while still staying alert to real heat danger.\u003c\/p\u003e\n\u003ch3\u003eKey benefits and practical use\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHardwired reliability with battery backup for continued operation during outages\u003c\/li\u003e\n  \u003cli\u003e135 degrees Fahrenheit fixed temperature plus 15 degrees Fahrenheit per minute rise for fast detection\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled sensing minimizes nuisance alarms in busy spaces\u003c\/li\u003e\n  \u003cli\u003eRemote testing and silencing capability with common household remotes (sold separately) for convenience\u003c\/li\u003e\n  \u003cli\u003e85-decibel horn provides a clear, audible warning that can be heard throughout typical living areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn practice, this heat alarm fits naturally in spaces where heat is expected or variable, such as near a furnace, water heater, or in a garage where tools and engines generate heat. The unit’s design emphasizes straightforward installation on a wall or ceiling, with intuitive controls that help you verify function and mute non-threatening alerts without reaching for the device itself.\u003c\/p\u003e\n\u003ch3\u003eInterconnectivity and identification\u003c\/h3\u003e\n\u003cp\u003eWhen integrated with a First Alert BRK network, the HD6135FB can interconnect with up to 12 other compatible alarms and six additional devices like bells, horns, repeaters, or door closers. If one unit triggers, all linked alarms sound, and a latching indicator shows which unit initiated the alert. This interconnected network can enhance awareness across multiple rooms or zones in a home or small workspace.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the box and ongoing upkeep\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOne heat alarm\u003c\/li\u003e\n  \u003cli\u003eOne 9-volt battery\u003c\/li\u003e\n  \u003cli\u003eUser’s manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMaintenance is simple: regular tests with the test\/silence feature help confirm functionality, while the battery can be replaced from an accessible drawer.
